Maintenance
Chemical Pump
Rebuild the chemical pump every 500 hours. This
involves changing the diaphragm, plastic disk and
check valves.
For the procedure, see the “General Service Adjust-
ments” section in this manual for details.
NOTE: Inspect chemical inlet tube strainer daily.
Chemical And Temperature Control Valves
Examine the packing nuts on all the chemical valves
every 200 hours. Keeping these valve packings
properly adjusted will eliminate possible leakage from
the valve stems and add to overall valve life.
For the procedure, see the "General Service Adjust-
ments" section in this manual for details.
Pressure Regulator
Lubricate the o-ring and bullet every 50 hours. Use o-
ring lubricant Part #86265430.
For the procedure, see the "General Service Adjust-
ments" section in this manual for details.
Vacuum Hoses
To assure maximum hose life, we recommend that the
hoses be washed out with clean water at the end of
each working day.
High Pressure Solution Hoses
Inspect your high pressure solution hoses for wear after
the first 100 hours of use. Inspect every 25 hours
thereafter. If hoses show any signs of damage or
impending rupture, replace the hose.
DO NOT attempt to repair high pressure solution
hoses! Repairing high pressure solution hoses may
result in severe burns and serious injury!
All high pressure solution hoses must be rated for 3000
PSI at 250°F. Thermoplastic hoses do not meet these
specifications and should not be used. Severe burns
and injury may result if the hoses do not meet these
requirements.
Optional Waste Pump-Out
At the end of each work day, make certain that you
remove any debris or sediment which may be inside the
waste pump by pumping fresh water through the pump.
Engine Coolant Replacement
The coolant should be replaced every year. This
coolant is an integral part of the heating system and
needs to be maintained as any other working part of the
system. We recommend that this procedure be accom-
plished by the following steps.
Draining Coolant:
1. Reference Kohler Manual for specific coolant
draining instructions. Drains are located at the
bottom of the radiator and on the engine block next
to the oil filter.
NOTE: Be sure that used coolant is collected in a
proper container and disposed of in accordance with
local laws.
2. After draining is complete, close both the radiator
and helicoil petcocks.
Replacing Coolant:
1. Fill radiator with 50/50 ethelene glycol anti-freeze /
water mix.
2. Start unit and set throttle to idle position.
3. As the unit warms up, maintain a full radiator with a
50/50 mix.
4. Open petcock completely on helicoil to allow any
trapped air to escape. When coolant runs out of
helicoil, close petcock.
5. Fill radiator with 50/50 coolant mix.
6. Re-install radiator cap.
7. Shutdown unit.
Check radiator overflow bottle. Add coolant to proper
"cold" level.
